____________________________Typical Operating Characteristics (continued)
(VCC = 3.3V, 250kbps data rate, C1–C4 = 0.1F, all transmitters loaded with 3k. Typical values are at TA = +25°C, unless
otherwise noted.)

10
RESET
RESET Output. RESET remains low while VCC is below the reset threshold, and for 280ms (max)
after VCC rises above the reset threshold.
9
INVALID
Output of the Valid Signal Detector. Asserts when no valid RS-232 levels are present on any of
the receiver inputs for 90s.
7, 8
R_OUT
TTL/CMOS Receiver Outputs (R1OUT and R2OUT)
5, 6
T_IN
TTL/CMOS Transmitter Inputs (T1IN and T2IN)
17
GND
Ground
15, 16
T_OUT
RS-232 Transmitter Outputs (T2OUT and T1OUT)
13, 14
R_IN
RS-232 Receiver Inputs (R2IN and R1IN)
12
FORCEON
Force-On Input. Drive FORCEON high to override AutoShutdown Plus, keeping transmitters on
(FORCEOFF must be high) (Table 1).
11
FORCEOFF
Force-Off Input. Drive FORCEOFF low to shut down transmitters and on-board power supply.
This overrides AutoShutdown Plus and FORCEON (Table 1).
